摘要
纤维的瘤胃降解是一复杂的微生物发酵过程,涉及到微生物对纤维的黏附、纤维的水解及最终纤维糊精的发酵。其中,微生物分泌的纤维降解酶至关重要。只有伴随足量酶的产生,才发生真正的纤维分解作用。本文将介绍微晶纤维素酶、羧甲基纤维素酶、纤维二糖酶、木聚糖酶等4类型纤维降解酶活性的测定方法。
Fiber degradation in the rumen is a profound process of microbial fermentation involving in microbial adhesion to fiber, fibre hydrolyzation and final fermentation of fibrous dextrin.Especially, all kinds of celluolutic enzymes excreted by microbe play a key role.Under the condition of enough enzyme,fiber was broken up formally.The methods of activity assay on four kinds of enzymes, such as cellulase,glucanase,cellobiase and xylanase,were introduced.
